James-F pointed me towards this thread and the patch and asked me if I could integrate it in my enhanced DOSBox builds. And so I did, so starting from Version r4003 PC speaker playback should sound better using my enhanced builds (see signature). 😀

Hope this helps. It looks like this patch generally improves accuracy in every test case I've tried, *except* this one. Are there any other regressions that anyone can see?

A bit late, but "Descent 2" has a problem with this patch when the PC speaker is disabled in the config. It won't start the intro sequence, even if the game isn't putting out sound over the speaker but over SB.

The game doesn't even use the speaker, it's just not starting when I disable the speaker in the conf-file, even if it puts the sound out over Soundblaster. It works with vanilla DOSBox, with the same conf, so it has to be a problem with this patch.
